Who would have thought that social tools like Facebook, instant messengers and text messaging would spell lost productivity? A study sponsored by harmon.ie found that 57% reported work interruptions are due in part to collaboration and social tools. Shocking stuff. What’s more worrying however, is that some of the respondents say that they can only work for 15 minutes before they get interrupted. Another worrying statistic is that if a worker loses an hour per day because of these interruptions (which isn’t a huge leap to make), harmon.ie says that it translates into $10,375 of wasted productivity per person per year, assuming an average salary of $30/hour. This is something that businesses need to be aware of, lest their employees get more concerned over their farms than the business at hand.
